Description

Technical Field

[0001] This utility model relates to the field of epoxy adhesive preparation technology, specifically an epoxy adhesive mixer for PET film. Background Technology

[0002] In the production and processing of PET film, epoxy adhesives are often used to bond and laminate the PET film to improve its performance and functionality. Epoxy adhesives are typically composed of epoxy resin, curing agents, and other additives mixed in a certain proportion. The uniformity of this mixing directly affects the adhesive's performance, and consequently, the quality of the PET film.

[0003] Currently, most equipment used for mixing epoxy adhesives is the ordinary stirring mixer. This type of mixer typically includes a mixing tank and a stirring paddle, and the mixing of the adhesive components is achieved by the rotation of the stirring paddle within the mixing tank. However, due to the differences in viscosity among the components of epoxy adhesive, and the tendency for stratification to occur during mixing due to insufficient stirring, ordinary stirring mixers cannot guarantee uniform mixing, resulting in unstable adhesive performance.

[0004] Therefore, given the shortcomings of existing epoxy adhesive mixers in terms of mixing uniformity, there is an urgent need to develop a mixer that can achieve efficient and uniform mixing of epoxy adhesives for PET films. Utility Model Content

[0005] The purpose of this invention is to provide an epoxy adhesive mixer for PET film to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] An epoxy adhesive mixer for PET film includes a mixing drum. A turntable is rotatably connected inside the mixing drum. A pair of stirring shafts are rotatably connected to the bottom surface of the turntable. The surfaces of the stirring shafts are respectively provided with helical blades in opposite directions. The opposite directions of the helical blades allow for material convection in opposite directions during rotation. Combined with the rotation of the turntable, this achieves multi-dimensional mixing of the epoxy adhesive components, solving the problem of uneven mixing caused by unidirectional motion in traditional mixing. Both stirring shafts are conical. A pair of first motors are mounted on the top surface of the turntable, and the output ends of the first motors are drively connected to the stirring shafts. A feed trough is provided on the top surface of the turntable, and the feed trough is connected to a feed pipe. The top end of the feed pipe penetrates the top surface of the mixing drum and is connected to a feed hopper. A drive unit is mounted on the top surface of the mixing drum, driving the turntable to rotate. The conical stirring shafts allow the blades to have different mixing ranges at different heights, thus taking into account materials at different depths within the mixing drum and preventing insufficient mixing of materials at the bottom or edges.

[0008] Furthermore, the driving component includes a second motor mounted on the top surface of the mixing drum. The output end of the second motor is connected to a drive gear, and a driven gear is mounted on the outside of the feed pipe. The drive gear and the driven gear are meshed together. The second motor provides power, and the torque can be increased through gear reduction to ensure that the turntable drives the stirring shaft to rotate stably, adapting to the stirring requirements of high-viscosity materials.

[0009] Furthermore, the feed pipe and the turntable are connected coaxially. The coaxial design ensures that the feed pipe coincides with the central axis of the turntable when the turntable rotates, avoiding shaking caused by eccentric rotation of the feed pipe and ensuring that the raw materials enter the mixing cylinder stably.

[0010] Furthermore, a limiting ring is installed on the inner wall of the mixing cylinder, and a limiting groove is provided on the side of the turntable. The limiting ring slides in the limiting groove. The limiting ring and the limiting groove cooperate to restrict the axial displacement of the turntable, ensuring that it rotates only in the horizontal direction, avoiding the turntable from shaking up and down due to the force on the stirring shaft, and improving the structural stability.

[0011] Furthermore, the side of the mixing cylinder is provided with several heat dissipation grooves, and the heat dissipation grooves are all located above the turntable. The heat dissipation grooves can dissipate the heat generated by the first motor in a timely manner.

[0012] Furthermore, a heater is installed on the outside of the mixing cylinder. The heater can heat the epoxy adhesive inside the mixing cylinder, reduce the viscosity of the material, and make it easier to flow and mix.

[0013] Furthermore, the bottom surface of the mixing cylinder is connected to a discharge hopper, and the bottom surface of the discharge hopper has an outlet. A valve body is connected to the outlet. The conical structure of the discharge hopper facilitates the concentrated outflow of the mixed epoxy adhesive, avoiding residue. The valve body can control the discharge speed and switch on / off, making it convenient to take materials as needed and preventing material leakage during the mixing process.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This epoxy adhesive mixer for PET film solves the problem of uneven mixing in traditional mixers: the stirring shaft with a pair of counter-rotating spiral blades generates convection, which, together with the revolution of the turntable, achieves all-round mixing; the conical design takes into account materials of different depths; the heater reduces the viscosity of the material and improves the mixing efficiency; the gear transmission and limiting structure ensure stable operation, and finally achieves uniform mixing of all components of epoxy adhesive, ensuring the bonding quality of PET film.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 - Figure 5 This utility model provides a technical solution: an epoxy adhesive mixer for PET film, comprising a mixing drum 1, a turntable 11 rotatably connected inside the mixing drum 1, a pair of stirring shafts 12 rotatably connected to the bottom surface of the turntable 11, and the surfaces of the pair of stirring shafts 12 are respectively provided with spiral blades in opposite spiral directions, both of the pair of stirring shafts 12 being conical; a pair of first motors 13 are mounted on the top surface of the turntable 11, and the output end of the first motors 13 is connected to the stirring shafts 12 for transmission; the top surface of the turntable 11 is provided with a feeding trough, and the feeding trough is connected to a feeding pipe 6. The top of 6 penetrates the top surface of the mixing cylinder 1 and is connected to the feed hopper 10. A drive unit is installed on the top surface of the mixing cylinder 1. The drive unit drives the turntable 11 to rotate. The epoxy adhesive raw material enters the mixing cylinder 1 from the feed hopper 10 through the feed pipe 6 and the feed trough. The first motor 13 drives a pair of stirring shafts 12 to rotate. The reverse spiral blades push the material up and down and inside and outside to convect. The drive unit drives the turntable 11 to rotate, so that the stirring shafts 12 revolve around the central axis of the mixing cylinder 1. The conical structure ensures that the material at different heights is stirred, realizing the all-round mixing of the raw materials and avoiding stratification or local unevenness.

[0023] As an embodiment of this utility model, the driving component further includes a second motor 7 installed on the top surface of the mixing cylinder 1. The output end of the second motor 7 is connected to a drive gear 8, and a driven gear 9 is installed on the outside of the feed pipe 6. The drive gear 8 and the driven gear 9 are meshed together. The second motor 7 drives the drive gear 8 to rotate, and the drive gear 8 drives the meshing driven gear 9 and the feed pipe 6 to rotate, thereby causing the turntable 11 to rotate synchronously, realizing the revolution of the stirring shaft 12, which, together with the rotation of the stirring shaft 12, forms a compound stirring.

[0024] As an embodiment of this utility model, the feed pipe 6 and the turntable 11 are connected coaxially. When the turntable 11 rotates, the feed pipe 6 rotates synchronously and concentrically with it. After the raw material enters from the feed pipe 6, it falls into the mixing cylinder 1 along the central axis direction, avoiding feed deviation or spillage caused by eccentricity.

[0025] As an embodiment of this utility model, a limiting ring 14 is installed on the inner wall of the mixing cylinder 1, and a limiting groove is provided on the side of the turntable 11. The limiting ring 14 slides in the limiting groove. When the turntable 11 rotates, the limiting ring 14 slides synchronously in the limiting groove. The mechanical limiting prevents the turntable 11 from moving up and down, ensuring that the revolution trajectory of the stirring shaft 12 is stable and does not affect the stirring effect.

[0026] As an embodiment of the present invention, the mixing cylinder 1 is further provided with a plurality of heat dissipation grooves 5 on its side, and the heat dissipation grooves 5 are all located above the turntable 11.

[0027] As an embodiment of this utility model, a heater 4 is further installed on the outside of the mixing cylinder 1. When the heater 4 is powered on, it generates heat, which is transferred to the material inside the mixing cylinder 1 through the wall, thereby increasing the material temperature, reducing the viscosity, enhancing the fluidity, and making it easier to be pushed and fully mixed by the stirring shaft 12.

[0028] As an embodiment of this utility model, the bottom surface of the mixing cylinder 1 is connected to the discharge hopper 2, and the bottom surface of the discharge hopper 2 has an outlet. The outlet is connected to the valve body 3. After the mixing is completed, the valve body 3 is opened, and the mixed epoxy adhesive is collected by the discharge hopper 2 under the action of gravity and flows out from the outlet. Closing the valve body 3 can stop the discharge, which is convenient for controlling the discharge amount or for mixing the next batch.
